Just to confirm what you have learned about aristocracy and their names, it was (and still is) quite normal for people to be referred to by title "as a name" rather than by their actual name. Thus John Smith who is the Earl (or Duke, Baron etc.) of Someplace would be also known as 'Lord Someplace', 'John Someplace' or just 'Someplace'.
An actual example is Prince Charles - one of his titles is the Duke of Cornwall but his name is Charles Windsor (he wouldn't be registered/baptised as Charles Cornwall). And his brother, though his title was the Duke of York, would still have the same surname of Windsor.
Therefore it's quite possible for siblings to have different titles, if their parents have enough titles to bestow on their children individually. However their actual surname would always remain the same.
To answer to your question, why don't you contact him again to ask about his sources? I had an ancestor I had been researching for ages, only to find her on someone else's tree. I contacted the lady to ask about her source and she replied that it was just a 'hint that popped up' and she had taken it as gospel. Needless to say I'm still searching! Your contact may have diligently researched everything, in which case you needn't reinvent the wheel. But equally, if you suspect some of his names and dates are impossible, it might be a load of old tosh.
You'll never rest until you know.
Have fun!
